Abstract
"LINHA DE ESCAPAMENTO E DE RECIRCULAçãO DE GASES, NOTADAMENTE PARA MOTOR DE COMBUSTãO INTERNA DE VEìCULO AUTOMOTOR". A invenção se refere ao escapamento e à recirculação dos gases nos motores de combustão interna, notadamente de veículos automotores, que compreendem um silencioso catalítico (2), meios (11, 12) de reciclagem dos gases de escapamento e meios (7, 8) de recuperação de calor nos gases de escapamento. Um trocador de calor (7) único é disposto para resfriar os gases de escapamento reciclados e recuperar a energia térmica dos gases de escapamento para o aquecimento do habitáculo do veículo e para proteger o silencioso catalítico (2) de temperaturas de escapamento muito elevadas. Válvulas (5) de derivação de gases de escapamento (8), de contra-pressão, e (12) de EGR são comandadas para isso por uma eletrónica de comando (13). Aplicação notadamente nos motores diesel ou a gasolina de injeção direta ou nos motores a gasolina de mistura pobre.
